Transdermal iontophoresis of dexamethasone sodium phosphate in vitro and in vivo: effect of experimental parameters and skin type on drug stability a…
2010
The aim of this study was to investigate the cathodal iontophoresis of dexamethasone sodium phosphate (DEX-P) in vitro and in vivo and to determine the feasibility of delivering therapeutic amounts of the drug for the treatment of chemotherapy-induced emesis. Stability studies, performed to investigate the susceptibility of the phosphate ester linkage to hydrolysis, confirmed that conversion of DEX-P to dexamethasone (DEX) upon exposure to samples of human, porcine and rat dermis for 7 h was limited (82.2+/-0.4%, 72.5+/-4.8% and 78.6+/-6.0% remained intact) and did not point to any major inter-species differences. Iontophoretic transport of DEX-P across dermatomed porcine skin (0.75 mm thic…
Survival benefit from recent changes in management of men and women with ST-segment elevation myocardial infarction treated with percutaneous coronar…
2019
Background: Nowadays, the majority of patients with myocardial infarction with ST-segment elevation (STEMI) are treated with primary percutaneous coronary interventions (PCI). In recent years, there have been ongoing improvements in PCI techniques, devices and concomitant pharmacotherapy. However, reports on further mortality reduction among PCI-treated STEMI patients remain inconclusive. The aim of this study was to compare changes in management and mortality in PCI-treated STEMI patients between 2005 and 2011 in a real-life setting. Methods: Data on 79,522 PCI-treated patients with STEMI from Polish Registry of Acute Coronary Syndromes (PL-ACS) admitted to Polish hospitals between 2005 an…
Sex differences in mortality in stable patients undergoing vasodilator stress cardiovascular magnetic resonance
2021
Abstract Introduction The prognostic value and therapeutic implications of ischemia as derived from vasodilator stress cardiovascular magnetic resonance (CMR) could differ in men and women, but it has not been stablished. Purpose We assessed the influence of the ischemic burden as derived from CMR on the risk of death and the effect of revascularization across sex. Methods We evaluated 6,237 consecutive patients with known or suspected chronic coronary syndrome (CCS). Extensive ischemia was defined as >5 segments with perfusion deficit. Multivariate Cox proportional hazard regression models were used. Results A total of 2,371 (38.0%) patients were women and 583 (9.3%) underwent CMR-r…
Autoimmune polyendocrine syndrome type 1: an Italian survey on 158 patients
2021
Abstract Background Autoimmune Polyglandular Syndrome type 1 (APS-1) is a rare recessive inherited disease, caused by AutoImmune Regulator (AIRE) gene mutations and characterized by three major manifestations: chronic mucocutaneous candidiasis (CMC), chronic hypoparathyroidism (CH) and Addison’s disease (AD). Methods Autoimmune conditions and associated autoantibodies (Abs) were analyzed in 158 Italian patients (103 females and 55 males; F/M 1.9/1) at the onset and during a follow-up of 23.7 ± 15.1 years. AIRE mutations were determined. Results The prevalence of APS-1 was 2.6 cases/million (range 0.5–17 in different regions). At the onset 93% of patients presented with one or more component…
CT-guided nephrostomy–An expedient tool for complex clinical scenarios
2018
Abstract Introduction & objectives Percutaneous nephrostomy [ 1 ] has emerged as a pivotal approach in the therapeutic management of the obstructed urinary tract. A consecutive incorporation of ultrasonic and radiographic guidance, the approach experienced an almost ubiquitious distribution while most centers currently applying either one or both of these tools jointly. However, success of ultrasound-guidance is limited in obese patients and non-dilated uropathy. In turn, fluoroscopy usually requires an opacification of the urinary collecting system by intravenous or antegrade contrast media injection, which might be harmful for already impaired renal function, raise intrapelvic pressure an…
The characteristics of patients with COVID-19-associated pediatric vasculitis: an international, multicenter study
2023
Objective: COVID-19-associated pediatric vasculitis, other than Kawasaki disease (KD)-like vasculitis in multisystem inflammatory syndrome in children (MIS-C), is very rare. This study sought to analyze the characteristics, treatment, and outcomes in patients with COVID-19-associated pediatric vasculitis (excluding KD-like vasculitis in MIS-C). Methods: The inclusion criteria were as follows: 1) age <18 years at vasculitis onset; 2) evidence of vasculitis; 3) evidence of SARS-CoV-2 exposure; and 4) ≤3 months between SARS-CoV-2 exposure and vasculitis onset. Patients with MIS-C were excluded. The features of the subset of patients in our cohort who had COVID-19-associated pediatric IgA vascu…
Intraspecific variation within Phlebotomus sergenti Parrot (1917) (Diptera: Psychodidae) based on mtDNA sequences in Islamic Republic of Iran.
2007
An intraspecific study on the morphological and molecular characteristics of Phlebotomus sergenti s.l., the main vector of Leishmania tropica, was performed on 28 Iranian populations from 11 provinces and a few samples from Greece, Morocco, Lebanon, Turkey, Pakistan, and Syria. Three morphotypes were identified as A, B and C, with some intermediate forms in the samples under investigation. Based on the number of setae and the width of basal lobe of coxite, differences between A and B morphotypes were highly significant. Excluding one unusual haplotype, sequence analysis of ∼439 bp of mtDNA (a fragment of cytochromeB gene, tRNA for serine gene, and a fragment of NADH1 gene) revealed a 6–7% g…
Percutaneous endoscopic gastrostomy in amyotrophic lateral sclerosis: effect on survival.
2010
Abstract Background Percutaneous endoscopic gastrostomy (PEG) is offered to amyotrophic lateral sclerosis (ALS) patients with severe dysphagia. Immediate benefits of PEG are adequate food intake and weight stabilization. However, the impact of PEG on survival is still uncertain. In this work we retrospectively evaluated the effect of PEG on survival in a cohort of ALS patients followed in a tertiary referral centre. Methods Between 2000 and 2007, 150 dysphagic ALS patients were followed until death or tracheostomy. PEG was placed in 76 patients who accepted the procedure and survival was analysed using the Kaplan–Meier life-table method. Results In ALS patients submitted to PEG, no major co…
Antithrombotic Therapy in Patients with Atrial Fibrillation and Acute Coronary Syndrome Treated Medically or with Percutaneous Coronary Intervention …
2019
Background: The safety and efficacy of antithrombotic regimens may differ between patients with atrial fibrillation who have acute coronary syndromes (ACS), treated medically or with percutaneous coronary intervention (PCI), and those undergoing elective PCI. Methods: Using a 2×2 factorial design, we compared apixaban with vitamin K antagonists and aspirin with placebo in patients with atrial fibrillation who had ACS or were undergoing PCI and were receiving a P2Y 12 inhibitor. We explored bleeding, death and hospitalization, as well as death and ischemic events, by antithrombotic strategy in 3 prespecified subgroups: patients with ACS treated medically, patients with ACS treated with PCI,…
Low doses of transdermal buprenorphine in opioid-naive patients with cancer pain: A 4-week, nonrandomized, open-label, uncontrolled observational stu…
2009
OBJECTIVE: The aim of this study was to evaluate the effect and tolerability of low doses of transdermal (TD) buprenorphine patches in opioid-naive patients with cancer pain. METHODS: This was a nonrandomized, open-label, uncontrolled study in consecutive opioid-naive patients with advanced cancer and moderate pain. TD buprenorphine was initiated at a dose of 17.5 microg/h (0.4 mg/d), with patch changes every 3 days. Doses were then adjusted according to the clinical response. Pain intensity, opioid-related adverse effects, TD buprenorphine doses, and quality of life were monitored over 4 weeks. The time to dose stabilization and indexes of dose escalation were also calculated. RESULTS: Thi…
